High transaction volumes causing problems for miners #2333

Description

@sammy007

There is tx spam ongoing, I see many blocks with up to 2 MB size with just ~50 tx. RPC getblocktemplate poll leads to timeouts (I have 5s timeout). This is not ok and I believe getblocktemplate must take less than 5s on decent hardware Intel(R) Xeon(R) CPU E3-1245 v5 @ 3.50GHz. Load average is 1.5.

You seems don't care about it, dev channel is silent and only cosmetic changes discussed there so far. It seems I must create a patch to ignore transactions at all and mine empty blocks if you are going to pretend that it's fine.

Consequences:

  • Mining centralisation
  • Empty block mining
  • Tons of orphans (uncle bs proposal can't help)
  • Tons of rejects
  • Fee market
  • Thousands of transactions hanging out in mempool
  • Full nodes shortage
  • Lazy mining leads to forks
